NCHAN

NCHAN gives the number of baseband channels. A baseband channel
is the smallest unit that was once an analog signal. One sideband from
one BBC is a baseband channel. Nothing prevents the user from
assigning several channels to the same BBC/sideband. In such cases,
the data in the two channels will be identical.

Argument: An integer.

Options: Any integer between 1 and the maximum number of channels which
on the VLBA is 16.
